2 OVERVIEW Microgrid applications are filled with complexities and challenges that are being overcome by the industry one hurdle at a time. Beyond the battles for microgrid ownership and their financial backing, the many technical complexities of maximizing microgrid applications have become pressing issues for utilities to embrace and understand. This conference will bring together industry professionals to share their experiences and knowledge on the technical challenges facing the integration of microgrids. Some of the technical issues coming to the forefront discussed in this conference and its workshop will be: integrating microgrids into the distribution grid through sophisticated controls, islanding of the microgrid, system inverters, the creation of accurate microgrid studies, and critical performance evaluation among others.

Normal street attire is appropriate. No protective equipment or clothing is needed. 10:30-10:45 am Return from Tour/Morning Networking Break 10:45 am - 12:00 pm Microgrids Technical Panel Discussion This panel discussion will dive into some of the technical challenges facing microgrids. The interactive discussion will cover a wide range of topics from: microgrid modes of operation, controllers, connections to the grid, testing and more. Doug Jones, PE, SCADA and Analytical Services Sr. Project Engineer II, POWER Engineers, Inc. Michael Grabstein, Renewable Energy and Infrastructure Consultant, Advanced Microgrid Solutions Eric Cotney, Vice President, Sales & Marketing, Axium Solar Jianhui Wang Ph.D., Section Manager - Advanced Power Grid Modeling, Argonne National Laboratory & Assistant Professor, Southern Methodist University 12:00-1:00 pm Group Luncheon 1:00-1:45 pm Interconnection, Integration, and Interactive Impact Analysis of Microgrids and Distribution Systems This presentation deals with some of the technical issues related to integrating microgrids into a distribution system and its DMS. It first describes elements of the operation of microgrids within distribution systems, including possible modes of operation and interactions in normal and faulted operating conditions. It provides background information, in the form of use cases, on some of the internal modes of operation of microgrids that may impact the distribution system, including normal and faulted operation. It then addresses operating modes in which the microgrid interacts with the distribution system, including power exchanges under normal operation and fault conditions as well as protection coordination. Finally, it discusses power system analysis tools, such as power flow and fault analysis tools that can be used to analyze the impact of the integration of microgrids in distribution systems.

5 AGENDA TUESDAY, AUGUST 22, 2017 (CONTINUED) 1:45-2:30 pm Protection Considerations at the Point of Interconnection for Grid Connected Microgrids Recent changes to IEEE 1547 Standard make certain allowances for intentional islanding and ridethrough allowances for voltage and frequency. We will look at the proposed changes and how this will affect microgrids interconnected to the area power system. Christopher Sticht, Senior Consultant, UC Synergetic 2:30-3:00 pm Networking Break 3:00-3:45 pm Engineering Challenges for Microgrid Performance Key system performance details that must be accounted for when designing a Microgrid include voltage and frequency stability, protective relay performance, ground source arrangement, and island detection. The engineering studies and tools used to quantify and improve the answers to these critical performance questions will be discussed. Lessons learned and examples from several Microgrids will be included. Dan Jones PE, SCADA and Analytical Services Project Engineer II, POWER Engineers, Inc. 3:45-4:30 pm Microgrid Studies Because many traditional simplifying assumptions used in power system analysis and planning break down in a microgrid environment, and because some of the complexities and issues associated with microgrids are relatively new, computer studies of microgrids are often critically important in de-risking, ensuring a successful deployment and diagnosing and correcting any problems that do arise. This presentation will discuss the various types of studies done, the modeling tools used including software and HIL, and what the studies can (and can t) tell you. Michael Ropp, Northern Plains Power Technologies 4:30 pm Closing Remarks and Adjournment Good opportunity for benchmarking, education and networking. Sr. Rate Administrator, ComEd It is a very good space for joining utilities, academia and industry to discuss the forthcoming trends of smart grids and its specific areas.
